Genetic and Physiological Characteristics of a Novel Marine Propylene-Assimilating Halieaceae Bacterium Isolated from Seawater and the Diversity of Its Alkene and Epoxide Metabolism Genes.

ABSTRACT: The Gram-negative marine propylene-assimilating bacterium, strain PE-TB08W, was isolated from surface seawater. A structural gene analysis using the 16S rRNA gene showed 96, 94, and 95% similarities to Halioglobus species, Haliea sp. ETY-M, and Haliea sp. ETY-NAG, respectively. A phylogenetic tree analysis showed that strain PE-TB08W belonged to the EG19 (Chromatocurvus)-Congregibacter-Haliea cluster within the Halieaceae (formerly Alteromonadaceae) family. Thus, strain PE-TB08W was characterized as a newly isolated Halieaceae bacterium; we suggest that this strain belongs to a new genus. Other bacterial characteristics were investigated and revealed that strain PE-TB08W assimilated propylene, n-butane, 1-butene, propanol, and 1-butanol (C3 and C4 gaseous hydrocarbons and primary alcohols)
